Filed: 2020-03-24
Abstract: To provide a plate type heat exchanger with less occurrence of clogging even when fluid containing a fibrous solid is circulated.SOLUTION: A plate type heat exchanger comprises a plate laminate comprising a plurality of heat transfer plates. In a peripheral edge portion of the communication passage of the plate laminate, an inflow preventing part and an inflow permitting part are alternately formed. The inflow preventing part prevents the inflow of fluid from the communication passage to between the heat transfer plates by causing hole peripheral edges of the adjacent heat transfer plates to abut with each other and sandwiching the gasket by the peripheral portions of the hole peripheral edges. The inflow permitting part permits inflow of fluid from the communication passage to between the heat transfer plates by providing intervals between the hole peripheral edges of the adjacent heat transfer plates and the peripheral portions. Two hole peripheral edges constituting the inflow preventing part causes inner peripheral side end edges to abut with each other in a state in which the other hole peripheral edges are inclined with respect to one hole peripheral edge.SELECTED DRAWING: Figure 9
